Could the amount of effort expended for class programmed dialogs be offset by using the command line with extremely well-written instructions? That is, spend the time writing better documentation.

Hi,

It's not easy to explain what I am trying to achieve, since it's still
yet not very clear for myself (:-)). I am still working on the
planning.

Simply put, in my project I am trying to build a stata interface
(GUI). It's ok for dialog programming (I understand basic
programming). But the boxes need to be refreshed and updated
constantly and I found out that this is better achieve via class
programming.

Adept and dasp are two software built on stata that show how to
achieve this, but when I go through the codes, its way to complicated
to understand. Reason why I've asked if there is a quicker way to
learn simpler examples.

I will therefore stick onto examining the codes, but will spend more
time on this. Hopefully, the adept and dasp authors will also have
time to help on my project, provided they have some time to devote to
me.

Here are the links:

Adept (Zurab et al.):

Dasp (Araar AbdelKrim):

Warmest regards.

Amadou.

As I'm mentioned here, I will just underline that, as I implied on 8
May, I've never used Stata class programming. I have sometimes found in
the past that writing an article on something was a good way to learn
about it, but writing anything on Stata class programming is not within
my plans at all.

More importantly, Amadou:

What precisely are you trying to do with Stata class programming?

What specific problems of understanding do you have?

This thread doesn't seem to have touched on any of these details.

(I don't what adept or dasp means here.)

Nick, Marteen [presumably Maarten], many thanks for your answers. I wish
someone with extended
knowledge on the topic (Nick, Zurab, Araar, statacorp staff, ???) could
write some tutorials on the subject. I need it to start a new project
and I've realized that I need to go through class programming (as in
the case of adept or dasp).

As I said, I get really frustrated when I tried official stata's class
programming examples (a search through the list shows me that this
issue has been already raised and solved).

It will be very useful if in their programming manuals, at StataCorp,
they took practical examples and developped all the codes from scratch
to end, as did Kit Baum in his books for mata programming (I've
learned better mata programming with his book than the Mata official
manual I've bought two years ago). I know there is the issue of the
volume size, etc., but a manual is precisely there for that, isn't it?

When I read in many stata manuals something like :

program
...
(the rest of your code continues here)
...
end

for my part is not very useful or appealling and can get the user
quickly
discouraged. This is certainly useful for advanced programmers who
need to go straight to what they need, but we the beginners need more
than that.

This is only my opinion, maybe other users do not feel that way.
